Tunnels

Veanco’s tunnelling experience ranges from cut & cover tunnels in urban environments for utility and transportation projects, to deep hard rock tunnels for road, railway or water conveyance. Projects, which were hampered by water inflows in excess of 500 l/sec at the face, deformations of more than 500mm, flowing ground conditions, ground freezing, and poisonous gas were all successfully tackled using solutions designed and executed by our team members. Projects were executed in high alpine terrain of more than 3,000m altitude, hampered by avalanches during the winter months.

Our team members have many years of experience in challenging conditions, both in drill & blast (NATM) tunnelling, as well as tunnel boring machine (TBM) construction.

For hydropower projects we provide all underground design services, from headrace tunnels to shafts, underground powerhouses and transformer caverns, and tailrace tunnels. Our engineers have experience in such complex underground works for hydropower projects over 500 MW capacity.

The magnitude of difficulties we experienced during the execution of a wide number of projects sets us apart from many competitors since we are convinced that these difficulties allowed us to perfect our skills, which have made us go-to experts in the field.
